The new Shimano 4700 Tiagra groupset follows it’s older brothers in looks, design and technology. The chainset features the 4-arm spider bringing it inline with 105, Ultegra and Dura Ace and the brake hoods on the levers do the same. The new Tiagra groupset offers better shifting and performance as well as being brought up-to date in looks, with the grey finish. An ideal choice if you existing Tiagra (old) groupset is looking tired or worn, of if you fancy an upgrade from another existing groupset. One last thing, two chainset options are available to you. Either the compact (50/34) or the mid-compact/ chainset (52/36) option and both in 3 crank lengths.
